Epidemiological comments | An epidemiological investigation is being conducted. The event includes 3 commercial layer farms. The birds showed: gasping, depression, lethargy, drooping wings, prostration, fever and death. The birds are 32, 72, 75, 84 and 94 weeks old. Isolates are being tested by intravenous pathogenicity test to determine their pathogenicity and by gene sequencing. Epidemiological investigation is on-going to establish the extent of the problem and the source of infection in order to implement additional measures to rapidly resolve the problem. Additional sampling is underway to identify the possible presence of other pathogens involved in the outbreaks. Note by the OIE Animal Health Information Department: H5 and H7 avian influenza in its low pathogenic form in poultry is a notifiable disease as per Chapter 10.4. on avian influenza of the Terrestrial Animal Health Code (2011). |
